The present invention relates to valves, through a central opening 20 with a chamand more especially to improvements in the her 21 that communicates through the open,- construction and operation of built-in valves ings 22 with an annular compartment 23 of used with bath tubs, shower baths, lavatory the casing 10, which compartment in turn fixtures and the like. connects with the outlet 12 througha pets 50 One of the essential features of the -insage 24. vention is to provide a built-in valve casing The outer end of thesleeve 17 is arranged with a main valve and a stop valve, which to extend an appreciable distance beyond valves are so associated that upon the rethe wall opening 14 and is provided with a moval of the main valve the stop valve will polygonal head or collar 25 for receiving 55 automatically cut off the supply through the any suitable tool, so. as to insert or remove casing. the sleeve from the casing.

A lateral suitable tool for inserting and removing tubular extension 13 extends outwardly the plug from the casing t 7 V 5 from the casing 10 through a wall or body A depending stop valve casing 35 ispre fso opening 14L and is interiorly threaded as at erably threadedly connected as at 36 to the 15. The casing 10 is also provided with plug 31, and is provided with a lateral an annular threaded portion 16 between the opening 37 which communicates with" the inlet and outlet ports; A sleeve 17 extends inlet port 11] for conductingthe supply to 0 axially within the extension 13 and is prothe casing. A stop or supplemental'valve s5 I vided at its lower extremity with tIl-(3Xt61'1 38 is mounted in the casing 35 and has a orly threaded section or partition 18 which tail piece 39 which isvslidably mounted in engages the portion 16 of the casing, and is a hollow annular boss 40 that projects from formed with a recess chamber 19 intheunthe bottom of the casing. Surrounding the der side thereof, which communicates tail piece 39 and the boss 40 is a coil spring i inlet to the outlet ports. Should it be degextension f42iforcesthe stop valve38 further tool isthen applied'to thepolygonal head 41 which tends to urge the valve 38 into engagement with the valve seat 33.

The main valve 29 is preferably provided with a depending extension 42 which projects axially through the plug 31 so as'to normally engage the top of valve 38 and maintain the same in its open position, to

permit the supply to flowfrom the inlet 11 through the openings 32, and 22 to the outlet 12 in the manner as indicated by the arrows,

sents a pleasing and attractive appearance.

The nipple'44i's preferably formed at its lower end'with an" annular guide or flange 48 which engages the valve stem 43 and'is H threadedly connected to the sleeve '17 above the flange 48 .as 'at 45.r-Preferably positioned between-the valve 29 and the annular guide 48 arethe washers 49 and the flexible packing 50'for insuring a tight joint be tiveenthe parts. Thef valve 29 and the extension 42 are movedlinto and out of posi-' tion, with respect to: the main valve seat by the actuation of a'h andle '51 that is suit-' ably'connected'as at 52'to'fthe valve stem 43. v lssuming the parts to'be in the position as shown, it will be noted'that. the main valve and the stop valve are open. That is to say,'the supplyis free to" pass from the f sired to cut oil the 'supply for any reason,

the handle 51 isactuated so as to bring the valve 29 into engagement with the seat 30,,

during which 'movement of thevalve 29 the away from its valve seat 33. r hen it. isfdesired to remove the mam valve 29 and its .associatedparts from the 510 the handle 51 1s first removed from the stein casingin order to inspector renew the same,

431and'the'cap 46 is withdrawn from engage:

' ment' with the nipple"44, thus allowing the withdrawal of the es'cutcheon' 47 so as to permit accessfl to thesleeve ,17. A suitable 44' oflthe' nipple 44so as topartiallyunscrew the latter from the sleeve 17, which then allows the stem 43 and the extension 42 to be backed out a sufiicient distance as to cause the valve 38 to be moved to its seat 33 by the pressure of the spring 41,, thus I completing cutting oif the supplythrough the casing.

v The lower washer49 in addition to serv- 7 acts as a stop to limit the outward movement of the valve 29 and thus prevents the stop 111g as a support for the packing 50 also valve 38 from being moved to its closed posi tion when the main valve is opened.

If after the main valve 29 and its associated parts are withdrawn from the casing,

it' is desired to remove the plug 31 and the stop valve casing 35, the same may readily be eflected'by the insertion ofa suitable tool, such as a socket wrench orthe like, in

the recess 34 of. the plug 31, so as to cause the withdrawal of the plug and stop valve from the casing through-the extension 13! 7 It will be seen that by reason of the present construction simple and eflicient means are employed for automatically cuttingofl'f.

the supply through the casing immediately upon the removal of the main valve and its associated parts.

Additionally, the various parts mayread- I ily be assembled or disassembled for the purpose'of inspection or renewal, while the escutcheon conceals all unsightly parts that might detract from the general appearance of the device when installed.
